  • Finding inspiration 
  • Investigating other artists' work
  • Mould making
  • Creating imagery with depth using stamps, powders, and decals
  • Divesting your piece
  • Firing schedules
  • Cold working


Workshop Outcome:

  • Multiple Glass Casts of Half Spheres 


How it Works: 

  • The course is made up of three live and interactive online sessions using the Zoom platform. You will find the zoom link via the week's chapters in the navigation panel. 
  • Silvia will give a step-by-step tutorial with demonstrations, and you will have ample opportunity to ask her questions during the live class
  • Each week they will demonstrate a technique for you to try between sessions
  • A member of the Glass School team will also be in the Zoom class to assist you and Silvia
  • Mix with Silvia and other students on our dedicated community page, open for the duration of the course. Then join our exclusive Glass School UK Online Glass Community Facebook group to continue to mix with those who have attended any of our online masterclasses
  • A materials list is provided in the course navigation panel, so you can purchase what you need to create your pieces during the course. You don’t need absolutely everything on this list to be successful, Silvia will discuss different ways to reach our technical goals


We believe that this is the best way to get the very most from the course, but if this doesn’t suit you that’s fine: - If you can’t get to your studio, you can still learn the techniques and benefit from Silvia's extensive knowledge without making the pieces during the course itself.

This is a live online masterclass, but in case a student experiences issues with internet connection during the live class, a recording of each live session will be available to view until two weeks after the final session. This cannot be downloaded or shared and is only available for this limited time. By participating you agree to be recorded for this purpose.

These recordings will be available in the course navigation panel.
